Joe Jackson, father and manager of Michael, Janet and the rest of the star-studded family, was hospitalized Friday and is reportedly in the end stages of terminal cancer.

Close family members, including his wife, Katherine, have been making bedside visits to the hospital, according to TMZ.

Doctors have reportedly said there is no further treatment for the cancer, a disease he had been battling for months.

If these are Jackson's final days, they are not without controversy, as DailyMail.com has reported some family members have been barred from visiting him, and Jackson is said to have made verbal instructions that he did not want family members to see his medical records.

Other reports suggested Jackson didn't want his family to see him in poor health.

Jackson, 89, has been battling various health conditions in recent years, sources said, including dementia, stroke and heart attack. He was also involved in a car accident last year.

The father-of-11, who was born in Arkansas and raised his family in Indiana, was most famous for forming The Jackson 5 – a pop musical group that involved his sons Jackie, Tito, Jermaine, Marlon and Michael, who later went on to become the King of Pop and the solo act behind hits like "Thriller," "Beat It," and "Billie Jean."

He also began his daughter Janet's career, helping her become a recording artist at just 16 years old.

But his reputation as a father to his children was widely criticized, as many family members later spoke out about grueling rehearsals that some described as abusive. Michael had been open in the past about beatings at the hands of his father.

He was fired as Michael's manager in 1979 and left out of Michael's will when he died in 2009 at age 50.

Jackson’s most recent public appearance was at the BET Awards in 2015. He was attending with his daughter, Janet, who received the Ultimate Icon Award.
